STS - 1

Technical Datasheet | Supplied by S V Plastochem
STS - 1 by S V Plastochem is an organo butyl tin mercaptide stabilizer found in the form of clear light yellow liquid. Provides outstanding light stability maintaining initial colors. It is an effective heat stabilizer for crystal clear applications and requires lower doses compared with other stabilizers. Suitable for PVC sheets, blow molding, rigid films, injection molding, calendaring and extrusion. It can be used for higher temperature processings. It is soluble in almost all organic solvents and insoluble in water. Recommended dosage of STS - 1 is 2 – 3 PHR for rigid and semi-rigid applications and 1 – 2 PHR for flexible and plasticized applications.

Hansen Solubility Parameters

[17, 4.1, 4.1]
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with STS - 1. A practical determination of these HSP values would provide higher certainty.
